抛出System.InvalidOperationException的Microsoft.Speech SpeechRecognitionEngine.setInputToDefaultAudioDevice()方法 [英] Microsoft.Speech SpeechRecognitionEngine.setInputToDefaultAudioDevice() method throwing System.InvalidOperationException

问题描述

我正在使用 Microsoft.Speech (不是System.Speech！)，我正在尝试将音频流的输入设置为我的麦克风，这是默认的音频设备，但会引发异常:

I'm using Microsoft.Speech (NOT System.Speech!) and I'm trying to set the input of the audio stream to my microphone, which is the default audio device, but it is throwing the exception:

'System.InvalidOperationException' occurred in Microsoft.Speech.dll but was not handled in user code

Additional information: Cannot find the requested data item, such as a data key or value.

这只是一个测试，理想情况下，我想将音频流设置为扬声器，但是，如果我可以使用它，则可以使用虚拟音频设备软件插入麦克风流.如果任何人也可以直接将音频流设置到扬声器，那 会很完美.

This was just a test, ideally I want to set the audio stream to my speakers, but if I can get this to work I can just use a virtual audio device software to plug into the mic stream. If anyone can also set the audio stream to the speakers directly, that would be perfect.

感谢您的帮助！
